Hi, Mrs MacMhuirich, and welcome to XMTS from the bottom end of Africa.
I believe the name Murray comes from the Forth of Moray. An ancestor of the Murrays was granted land there.
But since your husband has taken on the name MacMhuirich, you now also have it.
Actually, in Scots law a woman never does quite take on her husband’s surname. She remains a member of her father’s family and retains that name (for example Jean Lindsay will marry John Dalrymple and be known as Jean Lindsay).
Even as a widow, she will be referred to as Jean Lindsay, relict of John Dalrymple.
But another oddity of Gaelic is that mac means “son of”, and when it is applied to a woman it changes form to mhic.
So a daughter of yours could be referred to as vic vur-ich, as in Jane mhic Mhuirich.
Well, that is one way of looking at it. She might just as easily have the mhic added to your husband’s first name (whatever that might be in Gaelic).
But perhaps I am getting you a bit too involved here . . .
Regards,
Mike
